Hello,
I'm hoping someone can the mobile view of my logo is distorted. I've tried a CSS overide but it doesn't seem to be working. Can anyone help

Could you please provide me with a URL to your website, either here or via PM (click the “Private Message” text underneath my avatar) so that I may analyze it? It is a lot easier for us to diagnose issues when we have a live site to examine.
